Frequently Asked Questions
Q: What is the purpose of the 139994 lockwasher?
A: The 139994 is a split lockwasher designed to prevent fasteners from loosening due to vibration and equipment movement. It is commonly used on manual and electric pallet jacks, forklifts, and material handling equipment to secure bolts and screws.
Q: Which equipment brands use the 139994 lockwasher?
A: This lockwasher is compatible with manual and electric pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and Clark. It is a universal component found on hydraulic cylinders, arm assemblies, and load wheel mounting points across these brands.
Q: What is the material and size of the 139994?
A: The 139994 is a steel split lockwasher with a zinc-plated or stainless finish. Confirm the bolt diameter matches your equipment before ordering. Standard sizes range from metric M5 to M10 on typical pallet jack assemblies.
Q: How long does a lockwasher last before it needs replacement?
A: Lockwashers typically last the life of the equipment if the fastener is properly torqued and not subjected to extreme vibration. If you find loose bolts during routine inspection, replace the lockwasher immediately as it has lost its grip. Multiple loosenings reduce washer effectiveness.
Q: Can the 139994 be used with any bolt type?
A: The 139994 works best with hex bolts and machine screws. Do not use it with shoulder bolts or specialized fasteners without verifying clearance. Ensure the bolt is torqued to manufacturer specification so the lockwasher can grip properly.
Q: Is the 139994 corrosion resistant?
A: The zinc-plated version provides standard indoor warehouse corrosion resistance. For cold storage or outdoor use, request a stainless steel variant if available. Inspect quarterly in high-moisture environments to detect rust early.
